Fallout 3 Walkthrough & Strategy Guide

But it's not so! After messing with a nearby computer terminal, your father, the Enclave soldiers and the colonel all fall to the ground, as your father encourages you to leave immediately before reinforcements arrive. Upon speaking with Dr. Li, you'll be informed that your father unleashed a lethal dose of radiation to kill the Enclave representatives, taking himself with them. To make sure his death wasn't in vein, it's time to get out of here. Follow her as she leaves the rotunda. She'll then run up a corridor briefly before turning right towards another manhole cover. Access this manhole cover to begin traversing the Taft Tunnels.

Now, it's time to get your house in order before proceeding, especially because there are a number of ways you can proceed. We opted to do the right thing here and keep everyone alive, but you have the option of killing any of the characters who aren't Dr. Li, if you want to lighten your load a bit. Otherwise, keep them alive, speaking to each of them. You can arm Daniel, the rude guy (we gave him a .32 Caliber pistol), but what you do is up to you here. Ultimately, however, you'll want to speak with Dr. Li to get the lowdown on what's going on. She's freaking out, and she makes it very clear that her survival, and the independent survival of Project Purity depends on you.

We're assuming you kept everyone alive for the sake of this walkthrough. Talk to Dr. Li and tell her and her assistants to stay behind as you scout up ahead. This will give you a chance to collect some items and gain your bearings without having to deal with their constant annoying chatter. Go down the corridor ahead until it opens up into a more wide-open chamber. Ahead and slightly to the left, you can find a medical kit on the wall which holds Rad-X and a Stimpak. To the left of that, you can find Buffout and a Toy Car, but make your voyage on that side quick! You'll become quickly irradiated due to the radioactive waste barrels strewn around that side of the room if you aren't careful. Otherwise, there's not much else to gather here, so run back and get the team you have to protect, and continue down the corridor ahead.

From here, things will initially be safe and quiet, except for the random Enclave Eyebot, who will give away your location if you don't kill them quickly enough (since they are amongst the weakest enemies in the game, however, this shouldn't even remotely be an issue for you). The pathway is linear and you shouldn't have any pathway choices to make in the early-going. Be sure to grab the Lead Pipe, Dirty Water, and Whiskey en route to your first pathway choice. Should you go right, or go left? First, go left, telling your team to stay behind. You'll have to navigate through irradiated space once more, but on and around the radioactive barrels you encounter, you should find some Rad-X, RadAway and Turpentine, all of which is worth getting for your ever-growing inventory.

Go down the other route now, with your team in tow. Head all the way to the dead end, where a door must be hacked open via a nearby computer terminal in order to proceed. You must move quickly towards the door near the end of the corridor, because there are Enclave soldiers in an adjacent room on your left that don't know you're nearby. Keep everyone past the door as Dr. Li begins hacking the computer, which will take a while. If you have an insane hacking rating, you can do it yourself, but chances are you don't, so be patient (and quiet) as she hacks the computer. When she's successful, the door will open and you can proceed down to the next part of the corridor. Be sure to grab the Stimpak and other stuff from the nearby medical kit before proceeding.
